Provide concise syntheses for each of the following compounds starting from but-1 - ene. The source of all the carbonatoms in these molecules must be either but-1 - ene or any one carbon nucleophile/electrophile. (If you must use areagent that has more than one carbon atoms you must show the preparation of that reagent from but-1 - ene.) (a)Methyl propanoate (b) 3, 5- Dimethylheptan-4-one (c) 5-ethyl-7-methylnon-4-ene
